Introduction to AS571

Autonomous System Number (ASN) AS571 is a specific identifier allocated to an autonomous system (AS), which enables that system to engage in internet routing activities. An AS represents a group of IP networks operated by one or more network operators with a single, clearly defined external routing policy.

Ownership of AS571

AS571 is owned by the University Corporation for Atmospheric Research (UCAR). UCAR is a non-profit consortium of North American member colleges and universities focused on research and training in the atmospheric and Earth system sciences.

Main Operational Activity of UCAR

The main operational activity of UCAR, as the owner of AS571, is to support and advance the atmospheric and related Earth system science community. This involves managing the National Center for Atmospheric Research (NCAR) and providing research, observing and computing facilities, and a variety of services to support the scientific studies of the earth's atmosphere, land, oceans, and solar environment.

Establishment of AS571

There is no specific public record available regarding the exact date when AS571 was established. However, being allocated to an academic and research institution, it would have been assigned sometime after the establishment of the ASN system itself, which was introduced in the late 1980s.

Malicious Use of AS571

Regarding concerns about malicious intent such as hacking or spamming, there is limited publicly available information. However, according to data from CleanTalk, a service monitoring for spam and hacking activities, it appears that AS571 is not prominently associated with such malicious activities. The following details are extracted:

• No significant reports of abuse or malicious behavior detected recently for AS571 on CleanTalk's database.


• The absence of substantial negative records suggests that AS571 maintains a clean reputation online, likely due to the nature of its owner's operational activities.

It is important to note that this information may change over time and continuous monitoring is essential to ensure the security and integrity of any network.
